%description
The libpng package contains a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files.  PNG
is a bit-mapped graphics format similar to the GIF format.  PNG was
created to replace the GIF format, since GIF uses a patented data
compression algorithm.

Libpng should be installed if you need to manipulate PNG format image
files.

%package devel
Summary: 	Development tools for programs to manipulate PNG image format files.
Group: 		Development/Libraries
Requires: 	libpng = %{version}, zlib-devel

%description devel
The libpng-devel package contains the header files and static
libraries necessary for developing programs using the PNG (Portable
Network Graphics) library.

If you want to develop programs which will manipulate PNG image format
files, you should install libpng-devel.  You'll also need to install
the libpng package.
